How Onyx Odds works
Onyx Odds is a social sportsbook. The site looks similar to a regular online sportsbook, with odds available for football, basketball, and other sports.
However, you cannot place real money wagers at Onyx Odds. The site offers two currencies: Onyx Coins and Onyx Cash. We discuss how they work in the next section.
Onyx Odds is available in 41 states. Social sportsbooks are particularly popular in states that have not yet legalized traditional online sportsbooks, such as California, Texas, and Georgia.
Dual currency system
This chart highlights the differences between the two currencies you can use at Onyx Odds.
| Onyx Coins | Onyx Cash |
| These coins allow you to play for fun. You cannot redeem them for prizes. | These premium coins are eligible to redeem for prizes once you have used them to make a successful pick (i.e., once you’ve satisfied a 1x playthrough requirement). |
| You can buy Onyx Coins. The site will normally give you free Onyx Cash if you buy Onyx Coins. | You cannot buy Onyx Cash. You can only receive it for free via mail-in requests or as a gift if you buy Onyx Coins. |
| Onyx Coins allow you to sharpen your handicapping skills. You can also share any successes with friends. | The redemption rate is 1 Onyx Cash to $1. You need at least 20 Onyx Cash to redeem a real money prize. |
Redeeming Onyx Cash for real money prizes
You need to meet a 1x playthrough requirement before redeeming Onyx Cash for a prize. The minimum redemption limit is 20 Onyx Cash, which equates to $20.
For example, let’s say you use 50 Onyx Cash to pick a team to win at odds of +150. If that team wins, you’ll get 75 Onyx Cash. You can then redeem your 75 Onyx Cash for a $75 prize.
Follow these steps to redeem prizes:
- Click on your account balance and select “Redeem Onyx Cash.”
- Enter the amount you’d like to redeem.
- You can then connect your bank account and redeem eligible Onyx Cash for a prize.
- Onyx Odds will transfer the funds to you via ACH. This process takes up to seven business days, depending on your bank.
Available sports at Onyx Odds
Onyx Odds currently lets you make picks from four sports:
- Football
- Basketball
- Hockey
- Tennis
You can make picks on NFL and NCAA football games, but the site doesn’t offer college basketball. Onyx Odds doesn’t cover international basketball or hockey leagues, either.
Rivals like Fliff, Thrillzz, and Legendz offer a much larger range of sports and leagues. Onyx Odds is still a relative newcomer to the market, as it only launched in October 2024. For that reason, we expect to see it add more sports and leagues in the future.
College basketball, baseball, golf, and soccer are the most obvious potential additions. Rivals also cover motorsports, UFC, boxing, cricket, darts, rugby, lacrosse, and more, so Onyx has lots of options to expand. However, it cannot currently compete with key rivals.
Markets at Onyx Odds
Onyx Odds offers a reasonably broad range of markets. You will find a standard point spread, total points line, and moneyline for each game. There are also alternate spreads and totals.
The site offers a modest selection of props, too. For example, you can make picks from among player passing yards, receiving yards, or rushing yards for an NFL game. There are also team totals and total points lines on either half.
However, competitors offer a far wider array of options. For example, Legendz offers more than 100 markets on a single NBA game. As such, Onyx needs to broaden its offering to compete with the best social sportsbooks.
Quality of the odds
The odds at Onyx are pretty competitive. You’ll find standard juice sides and totals for NFL, college football, and NBA games. That means the site normally offers -110 on either side of a bet, or perhaps -108/-112.
By contrast, Fliff typically offers -115 on either side of a bet. As such, you’ll generally enjoy better value at Onyx.
However, some new rivals now offer reduced juice lines. For instance, Legendz often provides odds of -109/-106 or -110/-104 on either side of a point spread or total. That means Legendz takes a house edge of 3.35% to 3.63% on its lines, compared to the standard 4.77% at Onyx Odds.
Onyx Odds bonuses for existing users
Onyx Odds isn’t currently offering any bonuses to existing users. We did not find a daily login bonus, social media competitions, odds boosts, or any other promos when conducting this Onyx Odds review.
Once again, that could be because Onyx Odds is still finding its feet. More promos may materialize in the future.
The only exception is the mail-in request option. You can send a handwritten letter to Onyx Games LLC at 169 Madison Ave. STE 11498, New York, NY 10016, requesting free Onyx Cash. The company will then credit 5 Onyx Cash to your account.
Each participant can send up to 100 mail-in requests. Follow the template from the site’s sweepstakes rules.
Is Onyx Odds legal and safe?
Yes, Onyx Odds is operating legally. This is still a reasonably new site, but Onyx has a flawless security record so far.
Legality in the US
Onyx Odds is a social sportsbook that offers promotional sweepstakes play. To operate legally in the US, sweepstakes providers must remove one of the three elements of a lottery: chance, prize, or consideration.
Sites like Onyx Odds remove the element of consideration. That means you can’t buy Onyx Cash. You can only receive it for free via mail-in requests or as a gift when you buy Onyx Coins.
When you play with Onyx Cash, you’re participating in legal sweepstakes. Another example of a legal sweepstakes is the McDonald’s Monopoly game. That means you can legally redeem Onyx Cash for real money prizes at Onyx Odds. The site complies with sweepstakes law in each state it’s available in, along with federal regulations.
Security measures
The Onyx Odds site is encrypted. It has an up-to-date security certificate, and the privacy policy is robust.
As Onyx only launched in October 2024, it doesn’t yet have a long track record of keeping players safe. However, the site offers industry standard security measures. There is also a responsible social gaming section.
Purchase and redemption options
You cannot make traditional deposits and withdrawals at Onyx Odds. However, you can purchase Onyx Coins and redeem Onyx Cash for prizes.
Payment methods
Open your account balance to buy coins at Onyx Odds. You’ll see the number of Onyx Coins you’re buying, the price, and the number of free Onyx Cash you’ll get.
Here is an example: buy 10,000 Onyx Coins for $10 and get 10 free Onyx Cash. The minimum purchase is $10. At the other end of the scale, you can buy 500,000 Onyx Coins for $500 and get 500 free Onyx Cash.
When you select an option, you can choose a method and enter your payment details. Your options are Visa, American Express, Discover, Mastercard, Trustly, PayPal, and ACH. Payments are instant, so the coins will appear in your account balance immediately.
Prize redemptions
You only need to play your Onyx Cash through a single time before redeeming it for a real money prize. As mentioned earlier, the redemption rate is 1 Onyx Cash to $1.
The minimum amount you can redeem is 20 Onyx Coins. That equates to a $20 prize. This is a lower minimum redemption limit than you’ll find at many rivals. For example, the minimum is equivalent to $50 at Fliff and Thrillzz, and $100 at Legendz. As such, Onyx Odds may suit players with smaller budgets.
Onyx Odds will transfer the funds via ACH after you link your bank account. This process takes up to seven days, but it may be quicker, depending on your bank.
Tips for maximizing your Onyx Odds experience
These tips can help you play responsibly and have fun at Onyx Odds.
Play responsibly
Enjoy this social sportsbook in moderation. Don’t neglect your work commitments, family, friends, or other interests.
Remember that there’s no obligation to make a purchase. If you decide to buy coins, never spend money you can’t afford to lose. There are no guarantees of success, as anything can happen on the field of play.
Responsible players set a strict budget, known as a bankroll. They then practice sensible bankroll management. That means they only use a small percentage of the bankroll on each pick. Check out our responsible gambling page for more information.
Leverage bonuses effectively
Requesting Onyx Cash by mail is a great way to boost your bankroll. The company will add 5 Onyx Cash to your account if you simply send a handwritten request.
Make sure you follow the template from the site’s sweepstakes rules. Copy it carefully, as you won’t get the free coins if you make a mistake. Add the code correctly, and ensure your handwriting is neat and legible.
Onyx Odds vs. competitors
Onyx Odds needs to make major improvements before toppling its key rivals. These are some of the main issues:
- Add more sports. The site only lets you make picks from among four sports right now, whereas some competitors have more than 20.
- Increase the range of props. You can browse a huge variety of props at sites like Legendz and Fliff, so a wider selection of markets would help Onyx Odds compete.
- Launch a native app. Social sportsbooks like Fliff and Thrillz offer high-quality apps that you can download via the App Store or Google Play.
- Increase the range of bonuses. Most competitors offer a selection of ongoing promos, including daily rewards, no-cost social media giveaways, and purchase bonuses.
- Add some useful features. There are no stats or insights at Onyx Odds. Adding some value-added features would enhance the user experience and make the site more competitive.
Final verdict: Is Onyx Odds worth your time?
Onyx Odds is a promising social sportsbook, which is worth checking out. The site is neat, accessible, and well-designed. You’ll find competitive odds for the NFL, NBA, and NHL. There are a few interesting props, too.
However, rivals offer a superior user experience right now. You’ll get more bonuses, a wider range of markets, and more features at Fliff and Thrillzz. Meanwhile, sites like Legendz offer sharper odds, plus casino-style games.
Onyx Odds has the potential to become one of the top social sportsbooks. It offers secure prize redemptions, and the software looks impressive. If it improves in the key areas we listed above, Onyx should be well worth your time.
